I think the reason I like your videos so much is because not only do you describe how a process occurs but you also say keywords( words that a professor might want you to know on a test) in context. TYBASEDBIOLOGYPROFESSOR

Thank you so much for these videos. I am taking microbiology during the summer, which means it's a condensed course. That means every test covers 5 chapters and I have a test EVERY SINGLE WEEK. This doesn't leave a lot of time for explanations in class. I wasn't really understanding TRANSFORMATION and TRANSDUCTION, but after watching your videos I do. I'm grateful for them.

thanks for your explanation, but i wanna ask what is the different structure between competence bacteria and non competence bacteria? thanks
@BiologyProfessor2 жыл бұрын
Competent bacteria have had their cell walls and membranes destabilized in some way, which will allow a greater likelihood of taking up the DNA in the environment. Ways that will destabilize the cell membrane and cell wall are calcium chloride with heat shock, or electroporation.
@aidacarreterodominguez68709 жыл бұрын
Hi Biology Professor!!! Your videos are very clear, I understood everyithing you said. Though, it comes to my mind a question: When the plasmid is inside the bacterial cell, is it replaced/recombinated or just integrated or added?
@BiologyProfessor9 жыл бұрын
Often, the plasmid remains separate from the bacterial chromosome and some plasmids can be replicated and given to other bacteria cells through conjugation (kzbin.info/www/bejne/j6rGh3qnd9hkppI). The bacteria cells can also have more than one copy of the plasmid. It is also possible for the plasmid to be integrated into the bacterial chromosomes and replicated whenever the bacteria cell divides. The exact outcome depends on many factors, including the type of plasmid, the species of bacteria, the environmental conditions at the time, etc.

Hi biology professor......i have a doubt to clear.....i have heard that the DNA strand is taken up through a special protein complex in the cell membrane......and athe process requires calcium ions,...can u plz explain about it....
@BiologyProfessor8 жыл бұрын
Many bacteria naturally capable of taking up DNA via transformation do so with a special protein complex in their cell membrane. When cells are "made competent" in the laboratory for a transformation procedure, they are often "heat-shocked" to create holes in the membrane. Calcium is then used because it is a positively-charged ion and it will be attracted to negatively-charged regions in the bacterial membrane as well as to the negatively-charged DNA, helping the DNA to pass through the membrane.

Can you please give me an example when the bacteria change and gain new plasmid and become more pathogenic
@BiologyProfessor10 жыл бұрын
Hisham Kassim - E. coli is actually a great example. E. coli is present in many human bodies without causing disease (i.e. it is commensal). But many strains of E. coli have acquired plasmids that code for virulence factors like toxins that can be lethal. These include enterotoxins and shiga toxins. Other virulence factors some strains of E. coli have are a type of adhesin protein that allows them to adhere more easily to our cells. You can read more about this here: en.wikipedia.org/wiki/Pathogenic_Escherichia_coli#Role_in_disease

whats the differences between transformation and the lysogenic cycle
@BiologyProfessor9 жыл бұрын
DJ JohnDoe Transformation is when the bacterial cell takes naked DNA from the environment across the cell membrane, which may either be incorporated into its chromosome (for linear DNA) or left as autonomous DNA separate from the chromosome (for plasmids). The lysogenic cycle is a type of transduction where DNA carried by a bacteriophage (a virus that infects bacteria) is integrated into the bacterial chromosome. For my video on transduction - see here: kzbin.info/www/bejne/q3urYnptgql2a6c

Mam kya transformation same genera of species ke bich hota h
@BiologyProfessor6 жыл бұрын
I think you are asking "What would happen if the transformation occurred between two cells of the same species?" Is that right? if so, here is the answer - transformation can occur between two cells of the same species or between two cells of a different species. Even two cells of the same species can have small differences due to genetic mutations and these can be exchanged. One cell can even have acquired genes or entire plasmids that the other cell doesn't have, even if they are the same species, and these can be exchanged.
